BICYCLE -BELL.

SPECIFIUATION forming part of Letters Patent No. 642,071, dated January 30, 1900. Application filed October 20,1899. Serial No. 734,161. (No model.)

To all whom it may concern.-

Beit known that I, CARL A. BRINK, of Aitleborough, in the county of Bristol and State of Massachusetts,have invented certain new and useful Improvements in Bicycle-Bells; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to the bells used on bicycles and like vehicles to give notice of their approach. It is fully explained and illustrated in this specification and the accompanying drawings.

Figure 1 represents the bell attached to one arm of the handle-bars of a bicycle. Fig. 2 shows the bell with one of the gongs taken 01f to show the ringing mechanism inside. Fig. 3 shows the same as Fig. 2,with all the mechanism removed but the inner plate that is held fast by the lower gong in Fig. 1. Fig. at shows the position of the hammer on the back of the inner plate seen in Fig. 3. Fig. 5 is the same as Fig. 2, with the escapementwheel removed. Fig. 6 is a section of the bell, taken through on line 6 6 in Fig. 2. Fig. 7 shows a rear view of the escapement-wheel with the gear-whcel attached.

The construction and operation of the hell are as follows:

A A are two gongs, one of which, A, is attached to an adjustable band B, by means of which the bell is made fast to a handle-bar I). The gong A has a stud 0 made fast in its center, to the outer end of which a plate F, the shape of which is seen in Fig. 3, is removably attached. The plate F supports all the working parts of the bell, as seen in Fig. 2. The first of these parts is the plate J, that lies next to the plate F and swings on a pivot f, fast in the lower end of the plate F. The upper part of the plate J has an opening in it, on the upper side of which a segment 9 of internal gear-teeth is formed to engage with a gear cZ, held free to turn on the bushing g, which is held firmly by the screw b, that holds the two gongs together. The lower end of the plate J is extended down between the gongs to form a thumb-piece f outside to operate the hell by, and a closed spiral spring 8 has one end made fast to the end of an arm w of the rigid plate F, and the other end of the spring is secured to the plate J at y for the purpose of drawing back the upper part of that plate when it has been pushed over by the thumb-piece f.

Outside of the gear cl is an escapementwheel 11, to which the gear 01 is made fast, (see Fig. 7,) and both are held free to turn on the bushing. A pallet N is held on a pivot c at the top of the plate F, so as to engage with the teeth of the escapement-Wheel H and vibrate when that wheel is turned by the gear (I. A hammer o is held on the back of the plate F on a pivot at i, (see Fig. 4,) in which that plate is reversed, and a pin r, fast in the arm 0 of the pallet N, extends through a hole in the plate F and enters a hole in the hammer to communicate the vibrations of the pallet to the hammer 'u and cause it to strike the gongs, the hammer being bent so that one end will strike one of the gongs and the other end will strike the other gong; but it is left straight for a single bell. The two gongs are held together by a screw-stud I), held fast in the gong A and screwed into the stud 0, fast in the gong A. For greater permanency of bearing the pivots b, c, and t are held at one end by their respective plates and at their outer end bya portion of the plate turned over to form a loop, thus holding the pivots rigidly on each side of the working member.

The plate F, which holds the working parts, is removably held on the stud O by means of a collar a, fast on the inner end of that stud, and which collar has two notches 0 (see Fig. 3) made in its periphery, into which two projections 0, made on the plate F, fit snugly, so as to hold that plate and prevent it from turning when the bell is rung and at the same time admit of the plate F and the rest of the mechanism being removed when necessary.

To prevent the hammer from rattling, a portion of the plate J is turned down to hold a spring '15 (see Fig. 4.) and arranged to press on the hammer o and hold it still when the bell is not in use.

It will readily be seen that when the thumbpiece f is pushed over toward the left, the rack g at its upper end (see Fig. 5) will turn the gear (Z and the escapement-wheel II, fast on the gear, and cause the pallet N to vibrate, which will make the hammer vibrate by the pin in the cam and strike the gongs alternately by the two ends of the hammer, and by making the two gongs A and A of two different kinds of metal-as, for instance, one of brass and one of steel-a very pleasant ringing sound somewhat in the nature of chimes is produced. As soon as the pressure of the thumb is removed from the thumbpiece f the spring s, which was drawn out by the movement of the plate J, will draw that plate back, and the segment Q will turn the gear and the escapement-wheel H back again and ring the two'gongs the same as when the plate was first pushed over by the thumbpiece f.

When the bell is used with only one of the gongs A, which can be'done by pushing a washer and a screw passing through the washer and screwing into the stud O to hold the bushing g firmly against the plate F and keep the mechanism in place, the hammer U is then made straight, so that both ends of it will strike alternately on the single gong.

Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent- 1. In a bell, the combination of two gongs, a main plate removably attached to one of them, a hammer pivoted to said plate, and arranged to strike the gongs alternately, a pallet pivoted to said main plate, an escape- -ment-wheel held on a central pin and engaging with the pallet, with means for operating said escapement-wheel, substantially as described.

2. The combination of two gongs a main plate removably held on a stud fast in one of the gongs, a hammer pivoted to said plate, a pallet pivoted to said plate and connected by a pin to the hammer, an escapement-wheel held on a central stud and engaging with said pallet, a swinging plate pivoted to said main plate and having a toothed rack made on it, a gear-wheel fast on said escapement-wheel and engaging with the rack, a spring connecting the two plates and arranged to draw the swinging plate in one direction, substantially as described.

3. In a bicycle-bell, the combination of a gong a main plate attached to said gong, a

hammer pivoted to said main plate, a swing-' ing plate pivoted to said main plate, a spring attached to said swinging plate and arranged to press on said hammer and prevent it from rattling, and means for operating said ham mer to strike the gong, substantially as described.

4. In a bicycle-bell the combination of a gong, a stud fast therein, a main plate removably held on said stud, a hammer pivoted to said main plate, a pallet pivoted to said main plate, an escapement-wheel held on a central pin and engaging with said pallet, and means for operating said escapement-wheel, substantially as described.

In testimony whereof I have hereunto set my hand this 16th day of October, A. D. 1899.

CARL A. BRINK.
